PackScript
PackScript is a free, open-source command-line compiler for generating Minecraft datapack files.
What PackScript is
PackScript is a free, open-source command-line compiler for generating Minecraft datapack files. It uses Python by default, allowing Minecraft commands to pass through without requiring a separate command syntax. Function definitions can combine files and generate function tags, while the `dp` object creates, changes, or removes datapack files, including dynamically named files. The `capture_lines()` function gathers command lines into a list for “Only One Command” constructions. PackScript generates recipes, loot tables, advancements, and predicates. Compilation can produce a directory, ZIP, or JAR file; a JAR can apply the pack as a mod and can package a resource pack when an `assets` folder is included. The `init --modded` option adds Fabric, Forge, and NeoForge configuration. A VS Code syntax highlighter and Fabric auto-compilation mod are associated projects. It runs on Linux, macOS, and Windows, requires Python 3.12 or later, and is MIT-licensed.
